F$GETSYI()

F$GETSYU() is a lexical function that returns status and identification information about the local system (or about a node in the local mixed-architecture OpenVMS Cluster system, if your system is part of an OpenVMS Cluster).

Format

F$GETSYI (item [,node-name] [,cluster-id])

item

In addition to the items below, you can specify any system parameter.

Item	Return type	Information returned
AI	String	TRUE if after-image (AI) journaling is enabled; FALSE if disabled.
ALQ	Integer	Allocation quantity.
BDT	String	Backup date/time.
BI	String	TRUE if before-image (BI) journaling is enabled; FALSE if disabled.
BKS	Integer	Bucket size.
BLS	Integer	Block size.
CBT	String	TRUE if contiguous-best-try; otherwise FALSE.
CDT	String	Creation date/time.
CTG	String	TRUE if contiguous; otherwise FALSE.
DEQ	Integer	Default extension quantity.
DID	String	Directory ID string.
DIRECTORY	String	Returns TRUE or FALSE. Returns TRUE if it is a directory.
DVI	String	Device name string.
EDT	String	Expiration date/time.
EOF	Integer	Number of blocks used.
ERASE	String	TRUE if a file's contents are erased before a file is deleted; otherwise FALSE.
FFB	Integer	First free byte.
FID	String	File ID string.
FILE_LENGTH_HINT	String	Record count and data byte count in the form (
FSZ	Integer	Fixed control area size.
GBC	Integer	Global buffer count.
GBC32	Integer	Enhanced longword version of global buffer count with a per-file maximum size of about 2.1 billion for indexed files.
GBCFLAGS	String	Per-file management flags for sizing of global buffer cache. Returns PERCENT if global buffer count is expresses as a percent, DEFAULT if global buffer size is determined at runtime by an algorithm using two global buffer SYSGEN parameters (GB_CACHEALLMAX and GB_DEFPERCENT); or NONE if no per-file management flags are enabled for the file.
GRP	Integer	Owner group number.
JOURNAL_FILE	String	TRUE if the file is a journal; otherwise FALSE.
KNOWN	String	Known file; returns TRUE or FALSE to indicate whether file is installed with the Install utility (INSTALL). However, returns NOSUCHFILE if a file does not exist (for example, the file has been installed but subsequently deleted).
LOCKED	String	TRUE if a file is deaccessed-locked; otherwise FALSE.
LRL	Integer	Longest record length.
MBM	Integer	Owner member number.
MOVE	String	TRUE if movefile operations are enabled; otherwise FALSE.
MRN	Integer	Maximum record number.
MRS	Integer	Maximum record size.
NOA	Integer	Number of areas.
NOBACKUP	String	FALSE if the file is marked for backup; TRUE if the file is marked NOBACKUP.
NOK	Integer	Number of keys.
ORG	String	File organization; returns SEQ, REL, IDX.
PRESHELVED (Alpha/Integrity servers only)	String	TRUE if the file is preshelved; otherwise FALSE.
PRO	String	File protection string.
PVN	Integer	Prolog version number.
RAT	String	Record attributes; returns CR, PRN, FTN, "".
RCK	String	TRUE if read check; otherwise FALSE.
RDT	String	Revision date/time.
RFM	String	Record format string; returns the values VAR, FIX, VFC, UDF, STM, STMLF, STMCR.
RU	String	TRUE if recovery unit (RU) journaling is enabled; returns TRUE or FALSE.
RVN	Integer	Revision number.
SHELVABLE	String	TRUE if the file is shelvable; otherwise FALSE.
SHELVED	String	TRUE if the file is shelved; otherwise FALSE.
STORED_SEMANTICS	String	ASCII string that represents stored semantics.
UIC	String	Owner user identification code (UIC) string.
VERLIMIT	Integer	Version limit number. The value 32767 indicates that no version limit was set.
WCK	String	TRUE if write check; otherwise FALSE.

node-name

Specifies the node in your OpenVMS Cluster system for which information is to be returned. Specify the node as a character string expression. You cannot use the asterisk (*) and the percent sign (%) wildcard characters to specify the node-name argument.

cluster-id

Specifies the cluster node identification number for which the information is to be returned. To get information for all the nodes in a cluster, use the F$CSID lexical function to obtain each cluster system identification number, and use the cluster-id argument of F$GETSYI to gather information about each node.
